Abstract
Various vehicles are integrally evaluated in energy efficiencies, costs, the sustainability in combination with renewable energy, and the infrastructure transferability to the future vehicle system. Energy efficiency of the electric vehicle (EV) is the most excellent at 0.89MJ/km and plug-in hybrid vehicles (plug-in HV) have also better excellent at 1.03 of gasoline and 0.95 MJ/km of diesel than 1.1 MJ/km of the fuel cell EV (FCEV). Cost performance of plug-in G-HV and EV with 16 kWh battery show much more excellent than that of FCEV. EV as well as plug-in HV shows the good sustainability and the transferability, while FCEV has serious problems such as H2 supply infrastructure. Evaluated integrally, plug-in HV and EV with about 16 kWh battery are the most promising vehicles in the future. The sustainable vehicle system of plug-in HV in combination with the renewable energy such as solar and wind powers can be made by the following systems; one is that the part of the profit in the wind power side is transferred in the solar power side by the individual green electric power certificate and the other is that the part of the cost in solar power side is transferred in the electricity charge.
